Welcome to our Mad (Men) world! Newcomer Teyonah Parris stands out from castmates in stunning fitted dress at series premiere

It must be daunting joining the already established cast of a well-respected and critically-acclaimed TV show.

But if Teyonah Parris was nervous about joining her Mad Men castmates at the series six premiere of the programme in Los Angeles on Wednesday night, she certainly didn't show it.

The actress sported a stunning fitted dress and wore her black hair piled high on top of her head to create a dramatic effect as she joined January Jones, Christina Hendricks and Jon Hamm among others at the event.

out: Teyonah Parris made an impression in a stunning fitted dress with dramatic updo and strappy black heels for the season six premiere of Mad Men in Los Angeles on Wednesday night

Castmates: Teyonah stood out as she joined castmates (left to right) Christina Hendricks, Jon Hamm, Elisabeth Moss, Jessica Paré and January Jones at the star-studded screening

Teyonah plays Hamm's Don Draper's new secretary Dawn Chambers in the show, and said in a previous interview with New York magazine that she tried not to feel under pressure to play one of the first black characters in the show.

The star, who has previously appeared in shows including The Good Wife, said: 'I know that this show hasn’t had an African-American in the office and I know that comes with a lot of responsibility as to how I portray this woman, but I can’t think about that. I can only go in and do what I think this woman would do.

'I try not to think, "Oh, I have to represent every single black person in the world that was there in the sixties."

All-star cast: Teyonah is thought to have a much bigger role as Don Draper's secretary Dawn Chambers for the sixth season of the show

Sheer daring: January Jones vyed for attention in an unusual blue and cream Jonathan Saunders dress, which featured a half-sheer skirt

Nice save: The drop waist skirt of January's attire was
completely see-through, but featured extra layers of fabric at the back
to conceal her modesty

'I have to tell this one woman’s
story and what that was for her. I’m kind of on the fence because as a
black actress, there aren’t a lot of roles out there for us, and so you
see a great show and it’s like,

'Oh wow, I would love to be on that
show. Oh, but there are no black people on it. So that part is
frustrating and I understand that, but at the same time I don’t expect
to be a part of everyone’s story if it’s not true to the story that
they’re trying to tell.'

But while Teyonah certainly courted
attention in her dramatic outfit, she had some competition from her
equally stunning castmates.

surely shocked her Mad Men alter ego Peggy Olson with her daringly

in the show, displayed her long slender legs in a cream and blue spliced
dress with sheer hemline.

drop waist skirt of the attire was completely see-through, but featured
extra layers of fabric at the back to conceal her modesty.

the whimsical item complemented January's pale skin tone, the design of
the dress looked almost more appropriate for the ballroom or an
ice-skating ring.

Don would be proud: Handsome Jon would have certainly made
Don proud by wearing a dapper three-piece checked suit with matching tie
and crisp white shirt as he arrived with his longtime partner Jennifer Westfeldt

The long-sleeved attire looked sensational on the 30-year-old's slim figure and she highlighted her already tiny middle even more by cinching it in at the waist with a belt.

The Canadian star also wore monochrome two-toned shoes and slicked her hair back to reveal some pretty drop earrings.
